Question
Chapter 17, Problem 21A
To determine
To explain: The comparison between the atomic number of an element and the number of protons in its nucleus.
Expert Solution & Answer
Explanation of Solution
Introduction:
The atom consists of a nucleus that is positively charged and a negatively charged electronsrevolve around the nucleus in a regular orbits. Protons and neutrons together forms the nucleus of an atom. The number of electrons present in an atom is equal to the number of protons in that atom.
The atomic number of an element represents the quantity of protons existing in its nucleus. This is the singular characteristic of an atoms of a specific element. Number of protons is same in all the atoms of a given element and number of protons in the atoms of different element is different.
